I don't even think it'd be this direct except maybe in the begining.

You already can monitor things like heart rate via motion amplification and track how and when they go where. And probably many other minor factors I can't think about atm.

Gather up enough of those and you should be able to establish a very strong sidechannel into when a restaurant might have new items, its food quality and how it changes over time.

Like how long does a person of age range a, who entered on his own with heart rate x and left with heart rate y, stay if he liked the food vs him not liking the food. Or something like that...

In the end a few public cameras or other type of sensor might be all that's needed. Even if we were to fix our portable wiretaps, I dont think a global surveillance society is avoidable.

We need to built a society that can allow for a modern equivalent of privacy and rule of law within that reality. We might not be able to get away with going 5mph over the limit or accidentally keeping a pen anymore, but neither do we want speeding in our neighborhoods or all our pens gone. So what's the solution here? Random sampling who gets punished? Law breaking quotas? Increasing fines based on severity of the crime and assets and income? Figuring out how to measure intent? Replacing all punishments for minor crimes with corporal ones? idk
